2011 Hybrid Check Charging System

My 2011 with just over 91,000 miles died last night at a busy intersection with the check charging system warning. Had it towed to the dealer but they are closed today so they will see it tomorrow morning. The repair should still be under warranty but just in case I am looking for any advice from those that had to deal with this issue. I remember the old thread back from 2011. I was hoping I would never have this issue but...... So any advice would be greatly appreciated.

Thank you

I just had that replaced before I did a trip to Florida over the summer. I know they did not change the belt that runs the oil pump. Also what device do you all you use pull codes off the hybrid? I have a bluetooth device that I have plugged into the OBD II port but it will not pull any codes if the CEL comes on.

Repair going to based on what they find after doing a complete fault code search of all the on-board control modules,, want to say there 20+ module on a Hybrid, though a handfull not relevant to Hybrid function..

Need to know what module seen fault, and which circuit seen to be at fault

OBD-II only deal with engine control,, you need more advanced stuff to get into the various Hybrid control modules to recover DTC from memory

As noted previously,, OBD-II only involve engine and trans control..

You state you have Hybrid warning, thus OBD-II not likely going to get into Hybrid control system in most instance.. I have no involvement with 2nd/3rd party parts,, I am Hyundai dealer by day, so I just plug in GDS and "select all",, and let it run all modules for DTC

Heard from the dealer. It was a inverter. I think that is what he said. It was part of the hybrid system but not covered under the Hybrid warranty. It was only covered under the 60,000 mile warranty from Hyundai. Luckily I bought the extended warranty when I bought the car which covered the $600.00 part and labor. Now I have to decide to keep the car, trade it in on another, or buy a 3rd party warranty again to cover the hybrid system. Anyone know of a good 3rd party warranty that would cover the hybrid battery and parts?

I may be mistaken, but I am 99% sure the inverter IS the HPCU which is clearly covered under the 100,000 mile powertrain warranty.
SBR may be able to chime in on this but I think your service manager is uninformed about this.

100K Warranty says this:
"HYBRID SYSTEM Hybrid Battery*, along with the following Hybrid-Specific components that are directly attached to or integral to operation of the Hybrid Battery; Hybrid Battery Wire Harness; Battery Management System and Wire Harness; Blower Assembly; Electronic Air Compressor; Active Air Flap Active Hydraulic Booster; EV Fuse; Service Disconnect Plug; Power Relay Assembly; Hybrid Starter & Generator; Auto Transmission & Traction Motor including housing case; clutch and all internal parts; Hybrid Power Control Unit; Electronic Oil Pump Assembly; Electronic Water Pump with In and Out Hose Module"

That is what I asked? The service adviser admitted it was part of the Hybrid system. He said he checked all the Hybrid warranty documentation and said he could not find the part covered there. He did find the part covered in the 60,000 mile warranty documentation. So I wonder if the people that bought the 2012 and above with the lifetime warranty on the hybrid system if they really do have all items of the hybrid system covered.

<<< Hence, they wanted to sell me the extended warranty and such which would then cover all of it for the 10/100...

How much did they want ? ?[/QUOTE]

If I remember, it was something like $2500 and it sounded like a pretty good deal compared to the list price and it being all inclusive. I passed on it though myself because I'm just not a fan of extended warranty and such and fine with being my own repair shop if needed.

I bought one for my kid's Fusion from the Hyundai dealer where we bought it. For Consumers | The Warranty Group and https://www.mrclaims.net

Inside of the first thirty days we had $900 in fixes needed, mainly because the car had 40,000 miles and the previous owner had neglected to do an expensive TSB. As the Ford dealer had the dash apart they found the blower motor bearings were bad (I thought it was vibrating).

The extended warranty company did not have the paperwork on file from the dealer so we could not get the work pre-authorized. I called the Hyundai dealer and they re-faxed it to them. The warranty company asked if I would consider paying for the work myself and filing a paper claim because they had no computerized records they could authorize against. I agreed. (This all happened on the same day)

I filled out their forms and they paid every dime. Yeah, I am a fan of theirs.

For my '16 HSH I bought the 10 year 120,000 mile Hyundai HPP Platinum warranty from the dealer for $1,464.

Ok. Dealer called last night and said the Hybrid was good to go. I show up and take a look at the paperwork and it turns out it was a relay that went bad. Gave them back the keys to the rental that the warranty paid for and went in and paid the $56.00 I owed. Went out hopped into the car and hit the start button and I was greeted by the CEL and the Wrench icon light. Leave it running and went back into the service center and told them what just happened. They took it back to the back and ran the diagnostics and it is still throwing the same code. Long story short I left again in my rental and the Hybrid will be looked at Monday by the Hybrid tech that cleared it as fixed.

General Description

The Motor Control Unit (MCU) supplies AC voltage to both the Drive Motor and the Hybrid Starter Generator (HSG).

The Drive Motor provides output torque to the drivetrain and the HSG starts the gasoline engine.

--------------------------------------------------------------

DTC Description

The MCU sets P0A0D when an open circuit is detected in the DC high voltage cable circuit.

I've had 12V batteries that went bad at the connection of the post. Sometimes it would make the connection, other times not, and hence you have an intermittent issue. I changed cable ends and everything up stream on the vehicle, and eventually made it back down to the battery internal connection... New battery and that was solved...

Just heard from the dealer. They replaced the same relay again because corporate said they have had some bad relays come through the supply chain. The hybrid is still tripping the code even with the second relay. He also told me the Hyundai engineer that is now involved has another 2011 with the exact same issue they are trying to figure out. So if you have a 2011 this might be something you will have to deal with. I asked him how many miles were on the other 2011 and he said he did not ask the Hyundai engineer. I will keep everyone updated with what they come up with.

Ok. The saga of my Hybrid continues. I have driven my car a total of 4 days since the initial issue started. They fixed the relay and I continued to get a CEL. Turned out to be a loose wire. They fixed that and I drive off thinking the car is fixed. 4 days later I am at a clients and the car would not start on the first try. Turn it off and try to start it again and it starts with the CEL on again. Take it to the dealership and they say the hybrid safety switch needs replaced. I say ok and leave it there and drive off in the loaner again. Get a call 2 days later and they said we replaced the safety switch but that did not fix the issue. They pulled a new code I guess and called corporate and corporate told them to replace the Hybrid Control Unit. That is ordered now and the car should be ready on Friday.

Has anyone had the battery replaced as well when they replace the control unit? Should I ask for a battery replacement while it is still under warranty? I only have about 7,000 miles of warranty left and do not want to be screwed over at mile 100,001. For those that have had the Control Unit replaced did that fix the issues or did they continue on after the replacement? Trying to decide if I want to keep the car since it is paid off or trade it in if it will continue to be a problem.

Thank you

Luckily I have not had any problems at all since having the software repaired and the high voltage connectors replaced. The poster "CarTechDude" was really instrumental in helping many of us out personally, and then he just disappeared. I had kept in contact with him for a while via private messages but he just stopped posting. I am out of the bumper to bumper warranty but still have 4 years/30k+ miles to go on the powertrain portion of it, and I hope to never have to deal with that issue again. I truly hope they get you back up to normal soon. Good luck.
